This invention appertains to the art of pack- I aging liquids,primarily, construction of receptacles made of paper, composition sheetmaterial, or the like, employed a largely today in substitution forordinary glass I milk bottles.

It is known that upon the delivery of milk in bottles or paper or likereceptacles; during the period between the time of packaging the milk 10and its use, a certain amount of cream rises to the upper portion of thereceptacle. It is desirablethat this cream be separated from the body ofmilk beneath it in the receptacle, and some types of glass bottles havebeen designed to provide a sort of cream compartment at their' upperends. Generally heretofore, however, the separating of the cream fromthe milk has been required to be accomplished by tilting the receptacleand pouring the cream from the upper so end of the receptacle. A certainamount of guess-work is thus entailed since it is diiiicult to calculateaccurately the point at which the lower cream line begins or the uppermilk line termihates.

The object'of this invention has been to provide an adjustable andpreferably flexible spout member connected with the liquid receptaclefor the milk and cream, at a point between its ends, which point isdefined fairly accurately as so the separation line between the milk andcream.

The spout member used has its inlet connection with the receptacle atsaid particular separation line, and is, according to the invention,normally adjusted to lie closely against the side of the re- 35 ceptaclewhen not in use, and to have its upper open end sealed in one way oranother. When the contents of the receptacle, milk and cream, havereached the user and it is desired to pour off the cream, so to speak,from the milk, the

49 user is ableto merely pull the spout member away from its podtionagainst the side of the receptacle into a slightly downwardly inclinedposition, and this will have the effect of permitting the cream contentof the receptacle to pass a through the spout member into a pitcher orsome other vessel arranged to receive it.

The invention lies primarily in the peculiar construction of the spoutmember, its arrangement upon the receptacle, and the mode of sealingsaid spout member or adjusting it so that it is inoperative except forits particularly designed purp se.

In the accompanying drawing:

Figure 1 is a side elevation of one type-of re- 'uceptacle, such as madeof paper, or the like,

and especially to the 'mr, Serial st. mass 6 Claims. (01. 229-7)equipped with the spoutstructure of my invention, dotted lines showingthe spout as when pulled out anddown ready to be used for carrying a of!the cream at the top of'the receptacle.

Figure 2 is a fragmentary vertical sectional 6 view, enlarged, 'of theupper portion of the receptacle, bringing out more clearly the method ofsealing the upper end of the spout member when not lnuse.

Figure 3 is aview in elevation of a modified 10 form of receptacle andspout structure as well.

Figure 4 is an elevational view of. the spout structure and receptacleof Figure 3, certain portions of the receptacle being shown in section.

Figure 5 is a fragmentary perspective view 15 showing more clearly themanner of uniting the inlet end of the spout structure to the wall ofthe receptacle to which it is connected.

Figure 6 is a perspective view of the sealing member employed with thespout structure illustrated in Figures 3 and 4.

In the drawing similar reference characters refer to similar parts.

Describing the invention in detail in respect to the forms thereofillustrated in the Figures 1, 2, and 5 will first be referredto. Thereceptacle with which the invention is used may take the tapering formof Figure 1, or the cylindrical form of Figure 3, or many otherdifferent forms of the commercial receptacles such as are to commonly inuse today, with the exception of those made of glass or like ware. Thereceptacle is designated i and near its upper end is located thespout'structure which includes the spout member 2. This spout equippedwith a flange portion 3 at its lower inlet end seated against a paper orlike gasket 4 applied to the wall of the receptacle i internallythereof, see Figure 5. The parts 3 and 4 may be united to each other andto the wall structure 40 by the impervious coating substance that isusually applied to the receptacle 1 both interiorly and exteriorly.

The spout member 2 is preferably made of a paper or similar flexiblematerial, and lends it--' as self therefore to being united to thesimilar material from which the receptacle l is made. The spout member 2istubular, of course, and open at its inlet end to the interior of thereceptacle I, said inlet end shown in Figure 1 at t to be located 50approximately at the cream separation line shown in dotted lines inFigures '1 and 3 and designated At its upper end,'before use thereof,the spout member 2 is, according to Figures 1 and 2, interas d awing. 25

member 2 may begs locked with the upper end portion of the receptacle Iby being passed through a slit or opening and thus the upper extremityof the spout member projects into the receptacle asshown at 2a in Figure2. When so disposed, the body of the spout member lies flat against theouter wall portion of the receptacle I, the fact that the spout memberis made of paper or similar flexible material enabling the flatteningthereof so as to avoid its projection from the receptable any more thanabsolutely necessary. Owing to this flattened arrangement of the spoutmember against the receptacle, there is little likelihood of the samebecoming accidentally displaced from its normal inoperative position inthe ordinary handling of the liquids packaged in the said receptacles.

In order to drain the portion of the cream in the receptacle I above thecream line I, it is only necessary to break the sealing member 8comprising a label or like sealing member arranged over the upperendportion of the spout member 2. The said seal closes the opening in thewall of the receptacle I through which said upper end of the member 2passes. Upon breaking said sealing member 8 by simply pulling the sameoil the spout member 2 and the receptacle I, the memher 2 may be loweredto the dotted line position of Figure 1, and under these conditions theportion of the liquid in the receptacle above the so-calledcream-separation line 'I will pass out of the receptacle into a suitablevessel arranged to receive it.

In the construction of Figures 3 and 4 the upper end of the spout member9 is not inserted through an opening in the wall of the receptacle Iabut is merely disposed flat against the outer surface of the receptacleand covered by the sealing member I 8, the latter being of the formshown best' in Figure 6 and having a pulling tab II for facilitating itsremoval from a position adhering to the receptacle I and part 8, and inwhich position it closes the upper end of the spout, preventing air fromentering the same and affecting the fluid contents of the receptable Io.

. My invention is very simple in reference to the spout memberstructure, affords advantages in respect to the assemblage of thestructure upon the receptacle, and is especially advantageous in regardto the facility with which the spout member may be put into use for thepurposes described.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States, is-

1. In combination with a receptacle of the class described, a spoutmember carried by the receptacle and comprising a tubular structurehaving an inlet end united to and communicating with the interior of thereceptacle between the upper and lower ends of the same, said spoutmember bing flexible and pressed so as to lie flat against the outersurface of the receptacle.

2. As a new article of manufacture, a milk receptacle having combinedtherewith a spout member freely movable from a position in which it liesagainst the outer wall of the receptacle to a position in which it mayincline so as to discharges portion of the contents of the receptacle,said spout member comprising a tubular structure the inner end of whichis united to and in communication with the interior of the receptacle atapproximately the cream separation line of the receptacle when milk iscontained in the latter, the said spout member being normally foldedflat against the outer surface of the receptacle, and sealing means forthe outer end of said spout member. 3. A milk container as set forth inclaim 2, in which the sealing means for the outer end of the spoutmember closes the spout member as well as connects the same with thereceptacle.

4. As a new article of manufacture, a milk receptacle having combinedtherewith a spout member freely movableffrom a position in which it liesagainst the outer wall of the receptacle to a position in which it mayincline so as to discharge a portion of the contents ofthe receptacle,said spout member comprising a tubular structure the inner end of whichis united to and in communication with the interior of the receptacle atapproximately the cream separation line of the receptacle when milk iscontained in the latter, the receptacle having an opening in the sidethereof to receive the free or outer end of the spout member, andsealing means for closing the.

opening in which the said free or outer end of the spout member isreceived after the free end of the spout has been inserted therein.

5. As a new article of manufacture, a milk container of paper or likematerial, a spout structure carried thereby and made of paper or likematerial and comprising a tubular spout member sufficiently flexiblethat normally it lies pressed flat against the outer wall of saidreceptacle, connecting means between one end of the tubular spoutstructure and the receptacle establishing communication with theinterior of the receptacle, and securing means for holding the spoutmember flat against the outer wail of the receptacle.

6. A milk container as claimed in claim 5, said securing meansconsisting of a seal afllxed to the receptacle and closing the outer endof the spout member as well as connecting the latter to the receptacle.
